CHARLES H. OUMMINGS, OF PROVIDENCE, RHODE ISLAND.

AXLEELUBRICTOR.

SPECIFICATION forming part of Letters Patent No. 309,136, dated December 9, 1884.

Application filed September 2, 1884. (No model.)

To @ZZ whom t may concern: l

Be it known that I, CHARLns H. GUmrrNe-s, of the city and county of Providence, and State of Rhode Island, have invented certain new and useful Improvements in Lubricators for Vehicle-Axles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to lubricators for the axles ot' carriages, wagons, and all kinds of wheeled vehicles, the object of my invention being to avoid the necessity o f removing the wheel when lubricating the axle, and to sup ply a constant flow of lubricant to the axle.

A further object of my invention is to regulate the supply of lubricant, in order that waste of lubricant may be avoided.

To the above purposes my invention consists in certain peculiar and novel features of construction and arrangement, as hereinafter described and claimed.

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in

which- Figure l is a side elevation of one end of an axle with my improvements applied. Fig. 2 is a vertical longitudinal section of the same. Eig. 3 is a sectional view of the lubricating` cup in detached condition.

In the said drawings, A designates the axle 5 B, the bolster, and O the yokes which unite the axle to the bolster. a designates the spindle of the axle, which spindle is formed with a longitudinal channel, c', extending from the outer end of the spindle to a point considerably within the body ofthe axle, substantially as shown in Fig. 2.

cL at designate any suitable number (two bcing shown) of short channels or ducts, which extend laterally from the main channel a', and open at the lower side of the spindle.

At the inner end of the channel a is a vertical cavity, as, which is 'formed partially in the axleand partially in the bolster, and serves as the socket which contains the lubricating chamber, hereinafter described. The outer end of the channel a. is closed by a plug, at, which may be either permanently ixed or may be removable, so as to permit access to the channel for cleaning the-same. l

D designates the lubricating chamber or cup, which may be of substantially the shape shown in the drawings. This cup is forced or screwed into the cavity a3, so that the lower end of the cup is in direct communication with the inner end of the channel a. At its lower end the cup is provided with a disk, d, which closely rits within the lower end of the cup. Above the disk d is placed a similar disk, d, which rests upon the disk d, and is connected to the latter, so as to turn upon it, by a screw, di. Each disk has one or more vertical apertures or holes formed through it, and through which holes the lubricant flows from the interior of the cup to the channel a. It will be seen that as the disk d turns upon the iixed disk d the holes may be set more or less into or out of alignment, and thus the iiow of oil may be readily increased or decreased.

d designates a stem which extends vertically upward within the cup from the disk d', and d designates a removable cap, which fits snugly into the upper end ot' the cup so as to turn therein. The under side of the cap d* is formed with a straight transverse groove, into which the upper end of the stem cl3 enters, substantially as shown in the drawings. New, in using my improved lubricator, the cap d* is removed and the lubricant is run into the cup. The cap is then replaced, and by turning itin its seat the disk d is turned upon the disk d, so as to regulate the size of the opening or openings through which the lubricant passes from the cup to the channel a. rIhus the lubricant will ,iiow in exactly the required quantity constantly through the channel a and out of the duets c2, and the spindle willbe steadily lubricated, and no waste of lubricant need occur.

Having thus described my invention, I claim-- l. An improved axle-lubricator, consisting of asuitable cup containing aiixed and amovable disk, each having one or more apertures for regulating the iiow of lubricant, substantially as set forth.

2. The combinatiomwitha suitable cup hav ing a xed and a movable disk provided with ICO apertures for the escape of the oil, of a removdisks d d', the stem d3, and the cap d, substanable cap arranged to fit and turn in the top of tially as and for t-he purposes specified. 1C

the cup, and a stem arranged to transmit; the In Witness whereof I have hereunto set my movements of the cap to Jhe movable disk, I hand. e substantially as described. 3 CHARLES H. CUMMINGS.

3. The combination, with the axle having l W'tnesses: the channel a and ducts a2, the plug a4, and the M. F. BLIGH, socket a3, ofthe lubricator-eup D7 having the l J. A. MILLER, J1'.
